i have a 97 civic hx and the previous owner had obd2 harness with a obd1 jumper harness for the ecu (ecu p28)

the car runs but i can't use the throttle position sensor or map sensor
so if i plug it in it cuts off! and i have no clue what the previous owner did to it
if you guys can give me input ill post pics! and it has a z6 intake manifold on a y5 head!

Thanks!

Any pics? Is your map sensor on the tb? Pics of your setup.
